Is it possible to run esp_http_client & mqtt at the same time ?

[plusorc]

I'm trying to run MQTT for logging together with espHttpClient doing multipart post upload
for some reason this is not working at all

I have the http working very well without any issue
When I run MQTT, it connects to my mosquitto broker and subscribes , but
the espHttpClient stops uploading the data

So I believe my question is :
Is it possible to run esp_http_client while at the same time run esp_mqtt_client ?
